4 Application flied-February 21, 1521 serialub. 446,599. :Y

. This invention relatesto typewriting machines, and inore particularly to an auxiliary. paper-rollsupply to "be used 1ntconnect1on Y with listing work on bookkeeping machines,

equippedwithtally-strip mechanism. V

g In certain kinds of work, widetal lyrstrips are used in bookkeeping machines inconnecw tion with ledger posting and similar work; .It has been found, however, thatthis class off workis not sufficient in many cases to; 'keep'themachines in continuoususe dur ng vworking hours.- Consequently, it has beenv P p d t dol i g ork, uc a the h r-v ing I of checks, on; the bookkeeping machines when not otherwise 1n use, i r

In carrying out the present invention, provision may be made of an auxiliary paper.- rollsupplyat the rearofthe platen-frame;

NVhen the work,: in-which awide tally strip 118-.11S6d, is completed, the 0p er at1ve may rewind the tally strip fon-the delivery roll atqthe rear onmay; remove the tallyit' ;is;secured by screws passing throughholes strip fromthe platen in? any other manner The strip from the auxiliary paper-roll may then (be passed around the platen vand attached to the winding mandrel of the regu; lar tally-strip. mechanism, so that the stripmay, be wound thereonbythe line -spacing 1 mechanism asthe listing of the numbers or amountsproceeds, j

. Preferably, the {auxiliary paper-511 is carried by a bracket mounted near the lefthand-end of the rear paper-table, to which threaded into a plate or strap in backof the paper-table. I Preferably, also, the side plates 1 of the supporting bracket are so inclined to; the surfacefof the rear papePtable as to I prevent the edge of a work-sheet from being i interfered-with when the platenis reversely rotated.

mechanism, so .thatfa tally-strip may :be used to" receive carbon copies ofwork typed ong work-sheets, ai condensedfilist of-Qthe, totals of. allthe piecesof. work usuallybeing printed on the tally-strip. Mounted: on the brackets 25fand 26 whichform suppo rtsfor shafts 27 and 28 extending.g parallel' to the axis of the platen, the deliverysha-ft 28 be:

and;2 6;ina manner more fully-described in the ,patent ;to- Frederick .;A.l"Ha1t, No.- 1,281,160, igranted October-,8, 1918; :.lhe shaft 27 extends through side I plates 29. and: 80, respectively,,of the tally-strip supportends 14 and-15 ofgthe platen-framet;are. H

ing ,detachably mountedi on; the brackets25 1' ing frame, and the pl'ates29 and 301are' held in position by means of I the shaft 28extending through open-endedslots.3ltherein.1

The :talley-strip roll is 'mounted' on the ing use, extends around the platenjl2 tofa 41nandrelj32 may be: eifectedrby means of a link33 connectingthe line-space slide 23 with'an arm 34 mounted on said shaft- 27 and having thereon a pawl35 to engage a on a handle 46'; pivoted on said shait't'2 7.

The mechanism so far describedimay'bei substantially the same as that disclosed in: said patent to Hart. a

In orderthat listing of items, such as, for

fected' when tlie macliineis not otherwise use, provision may bennadewf a support 47' for a narrow-strip supply; mounted on the paper-table 16. The support 47 may consist ofaabase plate 48 to rest-ontheupper v snr faee oi the paper-table 16; two side*-plates'- 49 and-5Q'} and a plate- 5l conneetingthe sideplates 49 and 50} and extending upwardly from tlie base plate 48. Preferably, the support 4 7 isconneeted with l the paper-table 16f.
